4" 100mm Wall Vent Cowled White

4" (100mm) Cowled Vent Wind Baffle Grille

Ideal for mounting on an external wall that is in an exposed position and where an outlet will be open to bad weather. The baffled grille has two advantages; it stops wind from rattling the shutter and also stops back draft when an extractor fan is switched off.

Ideal for wind and rain protection.
100mm (4") diameter duct connection that fits standard ducting or wall sleeves.
Single blade damper for anti back draught.
Easy screw fixing and connection to ducting.
Duct cowling baffle and blade are easily removed for fitting & cleaning.
